
Whether the power grid is connected correctly and powered on

Check whether the communication of measuring equipment is normal
9.3.2 Non-Alarm Inducing Failure
Machine working noise is high

Check whether the power is in the normal range; Measure whether the grid-connected
current and voltage waveforms are normal; Check the replacement of cooling fans.
Network communication mode:

Please check whether the IP address, subnet mask and gateway are set correctly.

Check whether the communication line is through and whether it is well connected.

If all the above tests are normal and correct, try to replace the LCD monitoring board.
Serial communication mode:

Check the wiring, check all wiring is good, A/B has no connection.

Communication adapter does not match. Replace communication adapter and try
again.

Check whether the local address and baud rate are consistent with the host computer.
LCD screen cannot be switched on and off

Check the communication connection between LCD screen and DSP board
